Definitions

  • the invention is directed to a device for controlling the temperature of a fluid in the form of a pipeline having a first, central cavity for the medium to be tempered, and with a surrounding second cavity for a heating or cooling medium having at least one inlet and at least one outlet Passage of the heating or cooling medium.
  • the DE 31 05 406 A1 discloses a connecting element for double pipes. If you want to use this arrangement for temperature control of a medium, an external, lossy return the temperature control medium is required.
  • German utility model DE 90 13 315 U1 relates to a double tube heat exchanger, wherein the temperature control medium is not transferred to the terminals on the same end flanges as the medium to be tempered, and therefore relates to a farther lying prior art. Incidentally, a return flow of Temper mecanical forces is not provided here at all.
  • the DE 196 53 613 A1 does not relate to a piping system with a continuous flow of medium to be tempered between two end flanges, but a concentrated heat exchanger component without any end flanges.
  • the DE 10 2007 058 334 B3 shows a discrete heat exchanger and not a piece of pipe fitting together via mating end flanges to a pipe. Incidentally, a concentric leadership of various media is not provided here.
  • the problem initiating the invention is to further develop a generic device for tempering a fluid in such a way that the energy loss is minimal, in particular also in the region of a return of a self-contained circuit for a heating or cooling medium.
  • the solution to this problem is achieved by at least a third, integrated with the pipeline cavity for returning the heating or cooling medium, wherein the outlet of the third cavity is in the vicinity of the inlet of the second cavity and the third cavity is separated from the second cavity or is coupled via its inlet to the outlet of the second cavity.
  • An inventive part is further characterized by one, two or three flanges, corresponding to a pipe end, a normal pipe and a tee or branch piece.
  • all orifices of different cavities in the region of a flange are isolated from each other by separate sealing rings. This provides maximum safety, so that even when a seal breaks, another seal still protects against direct contact between different media. The then in the region of a flange outwardly swelling medium is then visually perceived, and it can counter or repair measures are initiated, even before a contact between the media involved has taken place. This may be advantageous because on contact on the one hand and heating medium on the one hand and tempering medium on the other hand, incalculable consequences occur can, for example, a sudden solidification of the medium to be tempered, or even a chemical reaction.
  • first, second and / or third cavity made of metal, in particular steel.
  • Metal has a good thermal conductivity and therefore allows an intense heat exchange between different, separated only by a boundary wall media.
  • a metal above a certain minimum thickness is extremely robust and dimensionally stable, so that the involved media can even have different pressures.
  • first, second and / or third cavity is designed in the manner of a bellows.
  • the outer sheath may be insulated, for example by a kind of cuff. Thus, the total heat loss to the environment can be minimized.
  • the first or central cavity has a circular cross-section.
  • a rotationally symmetrical pipeline offers maximum mechanical stability.
  • the invention allows the first or central cavity to be continuous for a pig. This is an emptying, cleaning and possibly inspection of the central cavity without disassembly of the entire system possible. This means in particular that no flaps or other elements should hinder the passage of a pig.
  • the central cavity can branch, for example in the form of a T-piece, so that the medium to be tempered can be directed to various processing, filling or shaping stations.
  • the first or central cavity can be opened and / or shut off, for example by a slide or a flap.
  • the mass flow in the central cavity can be controlled, for example.
  • the first or central cavity can be opened and / or shut off by a ball with a passage opening, the path for a pig remains open in the opened state.
  • the first or central cavity opens in the region of a flange in a central opening.
  • the invention further provides that the second cavity is bounded by two approximately concentric tubes. While the inner tube also represents the boundary of the first or central cavity, the outer tube serves the delimitation from the environment and is preferably provided on its outside with a thermal insulation.
  • the second cavity in the region of a flange opens not in the form of an annular opening, but in at least one simply connected opening, preferably in two approximately diametrically opposite openings.
  • a certain constriction of the flow cross-section for the heating or cooling medium arises, which is acceptable, however, especially if there are several such openings, for example two, three or four, which are preferably distributed at equidistant intervals along the circumference.
  • the third cavity is preferably formed by one or more tubes which extend within the second cavity.
  • Another advantage of the invention is that the distance between two tubes of the third cavity is smaller than its double distance to the center of the first cavity. Several tubes of the third cavity can therefore be combined on a comparatively small cross-sectional area, leaving room for special devices in the remaining cross-sectional area.
  • one or more tubes of the third cavity extend continuously between two flanges and open into both flanges.
  • the third cavity is used exclusively for the rear passage of the heating or cooling medium.
  • the standard embodiment can be found in particular on temperature-controlled pipelines without branch or tail.
  • These are preferably end pieces of the heating or cooling circuit - but not the central piping system, which is always open at each flange, so that the medium to be tempered can flow freely.
  • "transfer stations” where the medium to be tempered, for example, flows into a container or a machine, which is tempered either by its own heating or cooling device, or where the tempered medium is allowed to thermally adjust to the ambient temperature.
  • This embodiment can be further developed such that one or more tubes of the third cavity in the region of its free end (s) is bent / are, in particular bent in the same direction.
  • the free ends of the third cavity open into the second cavity; At this point is the turning point between the upstream and choirströmendem part of the medium. With the location of these free ends can therefore achieve advantageous properties: If these free ends are bent up to just below the uppermost portion of the second cavity, it can be achieved that the heating or cooling medium, the second cavity as far as possible or - ideally - Completely fill until it flows into the third cavity and flows back within it.
  • the mouths of several, preferably all, tubes of the third cavity should rest on the same portion of a flange delimited by two mouths of the second cavity. This corresponds to the preferred tube guide of several tubes of the third cavity, thus the purpose is to leave in the opposite section space for special installations - eg. In the range of a T or branch piece.
  • the flow velocity in the supply and return flows is approximately the same.
  • the Flow (second cavity) has a much larger cross-section than the return (third cavity). This has the consequence that the heating or cooling medium in the supply has sufficient opportunity to exchange its heat with the medium to be tempered, while the faster flowing in the return heating or cooling medium has little opportunity to heat with the leading portion of the medium exchange.
  • the heating or cooling medium can be selected, for example, from a group comprising water, brine, glycol, alcohol or oil.
  • plastics in particular thermoplastics
  • foods for example fats, margarine, chocolate, ice, etc.
  • the heating or cooling medium and / or the medium to be tempered is under pressure.
  • the boiling point can be increased, so that, for example, water is also suitable as a heating medium for temperatures above 100 ° C. At much higher temperatures oil should be the better alternative.
  • Fig. 1 is a kind of modular system for creating piping systems 1 for transporting a medium with simultaneous cooling.
  • Fig. 1 there is as a basic building block of such a system standard tubes 2 with a constant cross-section.
  • other fittings for example. Stopcocks od.
  • Stopcocks Like., Which, however, represent a modification of the basic standard pipe 2 substantially.
  • the standard tube 2 consists of two mutually concentric tubes, namely an inner tube 6 and an outer tube 7. These are the same length and in the region of their ends in each case by a flange 8, 9 connected to each other. Preferably, these parts 6 to 9 are welded together; but they could, for example, also be soldered or glued together.
  • the inner tube 6 encloses a first or central, simply connected cavity 10, while in the region between the two tubes 6, 7, a second, annular, at least two-fold contiguous cavity 11 is located. While only the medium M 1 to be tempered flows in the first cavity 10, the second cavity 11 serves to conduct a cooling or heating medium M 2 .
  • Each flange 8, 9 has substantially an annular disk shape, with a central recess 12 in the middle, which is approximately congruent with the cross section of the first cavity 10.
  • This recess 12 may be surrounded by an annular recess 13, for receiving a Sealing ring 14 to completely seal the flow path formed by the first cavity 10 for the medium to be tempered M 1 in the region of the joint between two flanges 8, 9 juxtaposed parts 2 to 5.
  • the outer periphery 15 of a flange 8, 9, however, has a larger diameter than the outer tube 7.
  • a plurality of bores 17 are arranged, which serve to pass through screws to screw together different parts 2 to 5 of the modular system.
  • the inner, annular region 18 of a flange 8, 9 between the inner tube 6 and the outer tube 7 has in the present example, two openings 19, 20, which are diametrically opposed to each other and for forwarding the leading heating or cooling medium M 2 in the area the impact between the flanges 8, 9 juxtaposed parts 2 to 5 serve.
  • the diameter of one of these recesses 19, 20 corresponds approximately to the radial distance between the two concentric tubes 6, 7.
  • These preferably circular openings 19, 20 should each be surrounded by a recess 21 annular, in which a separate sealing ring 22 fits.
  • a third cavity 25 is also provided.
  • This consists in the standard tube 2 of two relatively thin tubes 26, 27, which are arranged parallel to each other and within the second cavity 11.
  • the outer diameter of these tubes 26, 27 is smaller than the radial extent of the annular second cavity 11, so that the tubes 26, 27 bear against neither the inner nor the outer tube 6, 7. They are held within the second cavity 11 only in the region of the flanges 8, 9, with which they are connected, in particular welded, soldered or glued.
  • the flanges 8, 9 further openings 28, 29, as Fig. 2 can be seen.
  • These openings 28, 29 serve as openings of the third cavity 25.
  • Wie Fig. 2 however, these openings 28, 29 do not lie diametrically opposite one another, but approximate one another; in particular, they lie both in the same section of the inner, annular region 18 of a flange 8, 9, which is enclosed by the two mutually diametrical orifices 19, 20 of the second cavity 11.
  • the two flanges 8, 9 of a standard tube 2 - each seen from the outside - are not identical, but mirror-inverted, ie mirror images of each other. Because of this, the tubes 26, 27 of the third cavity 25 extend parallel to each other over their entire length.
  • These mouths 19, 20 are each surrounded by an annular recess 30, for the purpose of receiving a respective sealing ring 31, for example. From an elastic material.
  • a first, straight through channel is produced, namely the stacked central cavities 10, and also a second, straight through channel, namely the annular cavities 11 set against one another, and at least one, in the present case two, straight through channels, namely in each case the juxtaposed eccentric Tubes 26 and 27 in the first, central channel 10 flows to be tempered medium M 1 ; in the second, annular channel 11, the heating or cooling medium M 2 flows forward, and in the eccentric channels 26, 27, this flows back again.
  • the end piece 5 has a special feature: it serves to terminate a downwardly directed line section. In this case, the function of flow and return is reversed.
  • the heating or cooling medium flows M 2 in the flow initially past the inner tube 6 and then occurs at the free ends 35 of these tubes 33, 34 just above of the lower flange 36, but for the second cavity 11 has no mouths, but is completely closed.
  • fills the heating or cooling medium M 2 by further feed the annular cavity between the two concentric tubes 6, 7 and thereby tempered the medium M 1 within the central cavity 10. Finally, the heating or cooling medium M 2 swells to each other adjacent mouths 28, 29 out and up.
  • T or branch piece 3 Here, both the inner tube 6 and the outer tube 7 branch. While the cavity 10 for the medium M 1 surrounded by the inner tube 6 is thereby still simply connected, the tube 6 which branches between the two, can branch off. 7 enclosed cavity 11 for the medium M 2 in this case, even referred to as three-connected.
  • the flow direction within the second cavity 11 is somewhat different than in the standard tube elements 2 common. Because the leading medium M 2 is first performed within the branch piece 3 of two tubes 37, 38 down to the branching flange 39, without filling the actual cavity 11 in the branch piece 3.
  • the tubes 37, 38 each connect two of the diametrically arranged mouths 19, 20 of the different flanges 8, 39 directly to each other.
  • the medium M 2 first fills the pipe system connected at the bottom and then swells upwards again through the adjacent mouths 28, 29 in the flange. There are, however, in turn connected within the branch piece 3 tubes 40, 41, which lead back to close to the upstream (input) flange 8 and free ends there. At this free pipe ends, the medium M 2 then exits and now fills the actual second cavity 11 from the upstream terminal side, as is the case with the standard pipe sections 2. As the cavity 11 fills within the branch piece 3, the medium M 2 continues to flow through the downstream, diametrically located orifices 19, 20 into the next following, non-branching tube piece, in the example fig. 1 into the tail 4.
  • a particular embodiment of a balance tube 42 shows Fig. 4 , It can be seen that the pipes 6 ', 7' are designed in regions as bellows 43, so that the distance between the two flanges 8 ', 9' does not change, even if the temperature of the pipe section 42 changes. The resulting change in length is compensated in the region of the bellows 43 by a deformation (approach or removal of the beads).
  • the bellows 43 need not extend continuously from flange 8 'to flange 9' but may be limited to a relatively short section.
  • the internal structure of the compensating element 42 may correspond to the standard tube 2 Fig. 1 correspond.
  • the standard tube 2 may also be present in a bent embodiment; in such a bent tube, a bellows 43 is normally not required.
  • the inventive principle is designed such that the cavity 11 is automatically vented when filling with the medium M 2 ; Accordingly, it can be completely emptied if necessary even without disassembly.
